Add a helper function to copy a "collection group" back to the host #1310

Closed sethrj closed 2 weeks ago

sethrj commented 2 weeks ago

This refactors collection assignment semantics (the initial implementation wasn't allowed to use C++17's if constexpr) and adds a helper function to copy an entire state collection group back to the host for debugging.

Since this contains some rather low level changes to device code, I did run unit tests on wildstyle (CUDA) with debug-orange and ndebug-vecgeom.
